Stainless steel chemical storage tanks are designed to safely store and feed aggressive and corrosive substances such as acids, caustic soda (sodium hydroxide) and hydrogen peroxide into process lines with guaranteed leak-proof integrity. ÖNSA Makine manufactures these tanks using special alloyed stainless steels selected according to the type of chemical and the risk of reaction. With their high corrosion resistance and leak-proof workmanship, they ensure both environmental safety and preserve the purity of the chemical.

Technical Specifications and Capacity Options

ÖNSA Makine chemical tanks are manufactured with surface passivation and welding techniques suitable for the chemical characteristics of the substance to be stored (pH value, oxidation potential, etc.).

Capacity Range: Wide volume options from 500 litres to 100 tonnes.

Material Quality: Certified AISI 304 for standard applications, superior resistance AISI 316L stainless steel for highly corrosive acids and caustic solutions.

Functional Design: Mixer-equipped (agitator) for chemical homogeneity, multi-compartment structures for managing different products in the same tank.

Insulation: Polyurethane or rock wool insulation options to maintain the stability of temperature-sensitive chemicals such as peroxides.  

Safety Equipment: Leak-proof lids to prevent chemical evaporation, safety valves, overflow prevention level sensors, and immersion heaters.

Connection Elements: Special gaskets (Viton/PTFE) and valve groups resistant to chemicals.

Industrial Advantages and Areas of Use

Areas of Use:

•   Textile Industry: Storage of hydrogen peroxide, which plays a critical role in acid, caustic and bleaching processes used in dyeing plants.
•   Chemical Industry: Raw material storage, intermediate product reactions, and final product packaging lines.
•   Pharmaceuticals and Cosmetics: Storage of pure chemicals in sterilisation and production processes.
•   Water Treatment Plants: Chemical dosing tanks for disinfection and pH balancing purposes.
•   Food and Dairy Plants: Caustic and acid preparation tanks for CIP (Clean-in-Place) systems.

Advantages:

• Maximum Corrosion Resistance: The use of AISI 316 grade prevents tank perforation and corrosion from corrosive ions such as chloride and sulphate, ensuring decades of safe use.
• Health and Safety: The body structure, which has passed leak tests, and safety equipment minimise the risk of chemical leakage to zero, protecting the working environment.
• Pure Product Quality: Thanks to the inert (non-reactive) structure of stainless steel, the colour, pH value and purity of the stored chemical remain unaffected.
• Easy Maintenance and Cleaning: The smooth internal surface finish (polishing) prevents sediment build-up, making tank emptying and washing extremely practical.
• Flexible Integration: Compatible with automation systems, sensor inputs allow monitoring from central production management systems (SCADA/PLC).

Acid, Caustic and Peroxide Tank Prices

Chemical tank prices are determined based on the tank's total volume, the grade of stainless steel used (304/316), the material thickness, and the additional equipment (mixer, insulation, sensors). As ÖNSA Makine, we offer these high-security systems, manufactured directly in our own factory, at factory-direct prices, providing your businesses with both technological reliability and cost advantages.
